Now that savannah is back up after hardware failure, and since Matthew
confirmed off-list that this works, I'm checking in this.

Avoid Tandem/NSK's broken long long (without a symmetric unsigned
long long, it confuses gnulib).
* configure.ac (AC_TYPE_LONG_LONG_INT): Declare long long broken
if unsigned long long doesn't work.
* THANKS: Update.
Reported by Matthew Woehlke.
